Think about that. Two percent of all buyers make up the lion's share of your sales.

Numbers like those start to make a strong case for broader use of customer-relationship management among package-goods players who've questioned its applicability because of the high cost per consumer.

This means that even the narrowest of traditional markets are likely to fail. This small yet diverse bit is tricky.

Tools such as the one that I am developing with Laubacher will allow real-time diagnostics of a brand's multiple personalities. We can uncover these niche markets.

And then the real work actually begins. How do we reach these people when mass media will terribly overshoot and overspend. Then, how do we keep them among our 2%.

As Neff correctly identifies, relationships are the key. And compatible personalities are key to relationships. Think of this as a brand version of eHarmony: 29 dimensions of compatibility.

And you have to be careful not to drift. Once you establish your brand personality, you have to remain true to it. Google used to be one of my absolute favorite brands, but today I referred to them as the "Wal-Mart of the Web" due to their control of some of the features of this blog (Google owns Blogger).

I'm impressed with some corporate efforts on Twitter (e.g., @Starbucks). However, following 21,355 people (at present), this is more like a casual hook up than a committed relationship.

It's a great time to study communications. I'm counting the days until the word "Mass" is toppled from the front of my college like a statue of Lenin or Hussein.
